Benefits of technology

The present invention provides a slot antenna that improves upon previous designs. The antenna includes a substrate, a radiator, a signal-feeding segment, a signal-feeding end, and first and second extension sections. The first extension section is on one side of the signal-feeding segment and increases the bandwidth of the antenna, while the second extension section is on the other side and also increases the bandwidth. The technical effect of this design is improved performance and reliability of the slot antenna.

Problems solved by technology

In addition, as regards sizes of communication devices, space for designs is limited, which influences designs of the antenna.
However, the slot antenna 10 of the prior art occupies a large area, and the bandwidth of the slot antenna 10 is not sufficient, so the slot antenna 10 needs to be improved to fulfill utilization requirements.

Embodiment Construction

[0016]Please refer to FIG. 2, which is a schematic diagram of a slot antenna 2 according to an embodiment of the invention. A main operating frequency band of the slot antenna 2 is 2300 MHz˜2700 MHz, and the slot antenna 2 includes a substrate 20, a radiator 22, a signal-feeding segment 24, a signal-feeding end 25, a first extension section 26, and a second extension section 28. The substrate 20 includes a first plane 200 and a second plane 201 opposite to the first plane 200, and can be made of FR4 or other material. The radiator 22 is set on the first plane 200 of the substrate 20, and includes a first radiating segment 220, a second radiating segment 222, a third radiating segment 224, and a fourth radiating segment 226. As can be seen in FIG. 2, the first radiating segment 220, the second radiating segment 222, the third radiating segment 224, and the fourth radiating segment 226 are respectively perpendicular to an adjacent radiating segment, which means that the fourth radiati...

Abstract

A slot antenna includes a substrate, a radiator, a signal-feeding segment, a signal-feeding end, a first extension section and a second extension section. The substrate includes a first plane and a second plane. The radiator is set on the first plane of the substrate, and includes a slot. The signal-feeding segment is set in a position on the second plane of the substrate corresponding to the slot. The signal-feeding end is electrically connected to the signal-feeding segment, and is utilized for transmitting signals. The first extension section is set on a first side of the signal-feeding segment on the second plane of the substrate, and is utilized for increasing a bandwidth of the slot antenna. The second extension section is set on a second side of the signal-feeding segment on the second plane of the substrate, and is utilized for increasing the bandwidth of the slot antenna.

Description

BACKGROUND OF THE INVENTION [0001]1. Field of the Invention[0002]The present invention relates to a slot antenna, and more particularly, to a slot antenna for reducing an area, and increasing a bandwidth.[0003]2. Description of the Prior Art[0004]In recent years, as the wireless communication technology develops and expands, higher demands for wireless communication are increased. Since more information is transmitted through wireless network, a wide bandwidth of an antenna for transmitting and receiving wireless signals is necessary. In addition, as regards sizes of communication devices, space for designs is limited, which influences designs of the antenna.[0005]Please refer to FIG. 1, which is a schematic diagram of a slot antenna 10 utilized in a wireless network. The slot antenna 10 includes a substrate 100, a radiator 102, and a signal-feeding segment 104. The substrate 100 includes a front plane and a rear plane. The radiator 102 is set on the front plane of the substrate 100...
